Question

180. A ball of mass 2kg moving with velocity of 10 m/sec
strikes a stationary ball of 8 kg and sticks together. What is the
velocity of the composite mass after collision?
​

Answer 1

Answer:

20m/s.. is writee..

thnkx for support

Answer 2

Answer:

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i v 2 f = 2 ⋅ m 1 ( m 2 + m 1 ) v 1 i + ( m 2 − m 1 ) ( m 2 + m 1 ) v 2 i .
